To all whom it may concern:

' Be it knownthat I, D MoRA LIVINGSTON,

a citizen of the United States, and a resident of the city of New York,borough of- Manhatt'an,, inthe county and State of New York, haveinvented a new and Improved Machine for lVIakingCooler or RadiatorSections, of

which the followingis a full, clear, and exact description. V

Specifically my invention relates to an automobile machine for makingthe sections of coolers or condensers, particularly coolers for use inconnection withautomobile ve- 'hic les driven by water cooled internalcomcirculated.

My present invention, therefore, resides in certaln new and usefulprinciples of structure and coacting element organizatlon throughwhich-I am enabled by a series of In practically embodying my inventionI- make use of a pair of jaws and two alternately acting diesfor eachsheet or plate of metal, the jaws serving a three-fold func- From theseshaping devices the metal plate tion, to wit, to feed the metal, to holdit, and to serve as anvils against which the dies act to give the metalcorrugatedform.

is passed between assembling rolls which match .or assemble the sheets,and, finally, the assembled sheets pass to the seaming devices Thesedevices embrace the jaws with essentially the three-fold functionascribed to the first named or shaper jaws, the seamer jaws coactingwith the horizontal and vertical seamer fingers by means of which theprojecting side edges of one sheet are folded or clenched over thecorresponding sideedges of the other sheet, .thusfini shing theoperation.

The accompanying drawings illustrate as an example one manner in whichthe principles of my invention may be practically describe thispractical embodiment.

n said drawings Figure 1 is a side elevat-ion of the machine; Fig. 2 is'a rent end elevation of the same; F ig.'3 is an enlarged sectionthrough the shapingdevices on the line 3-3 of Fig. 2.; Fig.4 is a planview'of that part of one of theguides for the metal plate which isadjacent to the shaping jaws and dies, said view illustrating also thearm for shifting the position of the guides and one of the stripperswhich coact with the shaper jaws; Fig. 5 is a section on'the line 5--5of Fig. 4; Figs. 6, 7, 8 and 9 are fragmentary sections showing theshaper jaws embodied, and I shall now in specific terms and dies, theadjacent part of the metal guide and the strippers, and illustratingalso the metal during the shaping operation, said views representingfour successive periods in the operation of the parts illustrated; Fig.10 is a diagrammatic view showing the shaper jaws, strippers and apartof the plate guide, and also illustrating the knives which areattachedto the shaper jaws to slit the edges of one of the plates forthe purpose of facilitating the seaming opera tion; Fig. 11 is afragmentary perspective view of one of the plates when shaped, this viewillustrating the slit side edges of the said plate which aresubsequently to be bent over the corresponding edges of the matingplate; Fig. 12 is a plan view, of the rear end I immediately coact-ingelements; Fig." 19 is a. detail section of one of the horizontal seamingfingers on the line 19-19 of Fig.

and are respectively transverse sections.

through the complete cooler section on the lines 3333, 34-34 and 35-35of Fig. 32, showing sections of the top, bottom and side bins of thecooler. I

As shown best in Figs. 1 and 2, the machine is erected on a suitablebase 40, and the frame comprises parallel side members 41 extendingvertically and fastened to the base,

and braced against each other by tie rods 42 which are shown in Fig. 1but which to avoid' confusion areomitted from Fig. 2. Mounted in thefront end of the machine is a rotary prime mover shaft 43 fitted with abalance wheel 44 at each end outside of the frame sections 41. Saidprime mover shaft is joined by gears 45 with the upper and lowershajfir'shafts 46 so as to drive the said shafts. In the rear part ofthe machine a stud shaft '47 is mounted (see Fig. 1) to which isfastened a sprocket 48 driven'by a chain 49 from asprocket 50 on theshaft 43.

The stud shaft 47 is connected by a miter gearing, indicated by thebroken lines 51 in Fig. 1, with a longitudinally extending shaft 52centrally located in theframe and mounted in transverse walls 53thereof. From this shaft 52 is taken the motion which operates theseaming devices, and owing to the positive gear connection between theshafts 43,

46 and 52 I ihsure maintaining correct synchronism of operation betweenthe feeding elements of the shaper and seamer devices.-

' As shown best .in Fig. 3 the metal sheets, Which are indicated at aand a, pass in at the front end of the machinerespectively at the upperand lower portions thereof, and

run thigggh flat tubular guides 54. Said" guides have lugs 55 attachedthereto, and w' these are mounted loosely on transverse secured to theshaft 46. The cam 49 is 10-.

cated between the inner jaws of the two groups of shaper devices, andthe inner jaws of the two groups are connected by a retractile spring 58which holds the rollers of the jaws engaged with the cam, and by meansof this cam and spring the jaws 57 are given a back and forth movementaround the center of the shafts 56 and toward and from the metal plates.

60 indicates the outer .shaper jaws which are mounted in suitable guidesor supports 61 and reciprocate periodically in a direction longitudinalof the line of movement of the metal platesby means of elbow levers 62driven from cams 63 attached to the shaft 46,-and suitably fulcrumed onthe frame, as shown best in Figs. 4 to 9.

Each 57 and 60 is formed with two teeth 64 which are spaced apart sothat the teeth may inter-engage when the jaws are in.

the position shown in Figs. 7 and 9, and

* these jaws are also provided with anvil sur-' faces 65 which meet thefront ends of the The guides 54 are each formed with I an opening 66therein into which opening the working faces of the jaws extend duringthe operation of the shaping devices. The metal plate is corrugated inrectangular bends, as shown in the drawings, particularly Figs. 3

and 6 to 9, and theteth 64 are arranged to' correspond to thecorrugations so that the metal may be grippedfirmly between the two jawswhen they are engaged, as shown or stripping the metal from the jawsduring certain periods ofthe operation, I provide each jaw with astripper plate 67. Each. of these plates, as shown best in Fig. 4, isprovided with two transyerse slots or openings which receive the teethof the jaws so that the stripper plates may move relatively. to the jawsfrom the position shown in Fig. 7 to the position shown in Fig. 6 withrespect to the upper plate, and to the position shown in Fig. 8 withrespect to the lower stripper plate; Said stripper plates have headedpins in Figs. 6 to 9. For the purpose'of removing 63 attached thereto,and these pins operate in cavities 69 formed respectively in the jaws tolimit the movement of the stripper plates.

70 indicates springs which press the pins 68 outward tending to move thestrippers into their outer positions, as shown with respect to the upperplate in Fig; 6, and the lower plate in Fig. 8. Said. stripper plateshave their end edges respectively engaged with the upper. and lowersides of the guides 1 54 so that lateral swinging of the guides asbefore explained will cause or permit one or the other of the stripperplatesto movemecording to the direction of movement ofithe. guide. The.guides 54 arefijmoved a Kindtheir shafts 56 by means of arms; I(seenected thereto.

Figs. 3, 4: and 5 which arms arellocated at 1' each side of the guideand pivotally con- The arms are fastened to shafts 72 which extendtransversely in the frame, and have arms 73 attached thereto, the arms73 being rocked by means of race cams 74 between which the arms 73extend. In this manner as the arms 73 are rocked the shafts 72 are movedback and forth, and through the arms 71 the guides 54: are operated. i

Each group of shaper devices is provided with two dies 75 and 76 (seeFigs. 3, and 6 to 9). These dies are arranged to act alternately andalong lines intersecting at right angles, the operation being such thatthe die that the jaw 57 has been moved inward, as

position shown in Fig. 7.

75 coacts with the anvil surface of the jaw 60, as shown in Fig. 3, andthe die 76 coacts with the anvil surface 65 of the dies 57, as indicatedby the broken lines in Fig. 7. The jaws 75 and 7 6 are given theiralternate movements by means of elbow levers 77 which rock looselyaroundthe shaft 72 and have arms 78 to which forked links 79 are articulated.The forks atthese links 79 straddle the shafts 46 and are operated bycam grooves in the outer walls of the cam disks 74, as indicated by thebroken lines in i Fig. 3.

In the operation of the shaper mechanism, corrugations are first startedin the ends of the metal plates in any manner suflicient to enable theplate to fit between the intermeshing teeth 64 of the shaper jaws in themanner shown, for instance, in Figs; 7 and 9. Assuming this .tohave beendone and shown in Fig. 6,. it will be seen that the springs will causethe stripper 67 of the jaw 57 to strip the metal from the teeth of .saidjaw while the guide 54. retains the corrugated plate in engagement withthe teeth 64: of the jaw 60. The parts being in this position said jaw60 will then be moved forward by its operating mechanism, as indicatedby the arrow and broken lines in Fig. 6, the jaw 60 then takingthe'advanced After this is accomplished the jaw 57 returns inengagelnent with the jaw '60, bringing its teeth 64: down between theteeth of the jaw 60, and clamping the corrugated metal between-the twojaws. The said forward movement of the jaw 60will result in advancingthe metal the width of. one corrugation, and the metal will then projectstraight from the first tooth 64 of the jaw 57, in juxtaposition to theanvilsurface'65 of said. jaw. \Vhen the parts assume this position thedie 76 will.

movement of the plate.

n a tch e d together.

move away from the jaw 60 to the position shown in Fig. 8. The stripperplate 67 of the jaw 60 now follows the guide 54 with the result that thecorrugated plate is entirely disengaged from the jaw 60 and held inengagement with the retracted jaw 57 by the guide 54. \Vhen this takesplace the rearwardly advanced jaw 60 now returns to the former position,as indicated by the arrow and broken lines in Fig. 8, and when this isaccomplished the jaw 57 and the guide 54 Y again return to their activepositions, as shown in Fig. 9. This leaves the metal plate extendingfrom the front tooth 64 of the jaw 60 and bridging the anvil surface 65of said jaw. The die now moves, as shown by the arrow and the brokenlines in Fig. 9,. and forms a second double bend in the plate, as thedotted lines in said view illustrate. Fig. 3 shows the die in the courseof this operation. From the position shown in Fig. 3 the die 75 returnsto its inactive position and then the jaw 57 is retracted and the jaw 60moved rearward repeating the operation, the beginning of which isillustrated in Fig. 6. It will thus appear that each time that the jaw60 moves rearward it carries with it the metal plate, feeding the samefor adistance equal to the movement of the jaw, the plate being thendisengaged from the aw toallow the aw to return and recover itsengagement with the plate. Also each time that the jhW 60 moves to itsrearward position the die 76 operates, as in Fig. 7, and each time thatthe jaw moves to its rearward position the die 75 operates as in Fig. 9,the shaper mechanism, therefore advancing the plate with a step-by-stepmovement and forming two double bends therein for each advanced Duringthese operations the stripper plates act to disengage the metalalternately from the jaws, whilev the guide acts to control the actionof the stripper plates and also to hold the metal engaged with one orthe other of the jaws according to the period of the operation. Inconnection with the formation of the corrugations'in the metal it isimportant to observe that the metal is shaped by bending or folding. ascontradistin dished from drawing, the former operation producingaccurate results and avoiding stretching and weakening the metal.-

Fig. 11 shows the lower plate a after it has passed through the shapingdevices. 30 shows the two plates after' being passed through the shapingdevices and It will be se n that in addition to the corrugations theplates are form d with off-set portions or shoulders indicated at 6.These shoulders or elf-sets are formed by suitable surfaces on the jawsor diesWimultaneously with ,the formation of the corrugations. Also toenable the side edges of the platesto be seamed together, the edges ofthe lower plate a are slit at each bend, as indicated at b. This iseffected by means-of small knives or blades 80 which are attached to theteeth 64 of the .lower jaws 57 and 60 and each time said aws areengaged, as shown in Fig. 10, the blades 80 strike through the plate aforming the slit bf as described. --Since it is only necessary to .slitthe edges of the lower plate a the lower shaping devices only areprovided with the knives or blades 80.

The two groups of shaping. mechanism operate synchronously so that thefnetal plates are corrugated and advanced-toward the rear end of themachine at the same rate of speed, the rear ends of the guides 54deliverin'g the corrugated plate between a i vbranching guide 81 androllers 82 (best shown in F i 3). The corrugated plate is by means 0.said guide 81 and rollers 82 -'-matched together in the relativeposition illustrated in Fig; 30,- the. relative sizes of thecorrugations of the two plates being gaged so that the plates will fittogether, as shown, and the edge portions of the plates by means of theshoulders h before described being caused to contactwith each other tofacilitate forming theseam, as will be here inafter described. Themiddle portions of the plates are spaced or separated from each other bythe shoulders b, as shown in the sectional portions of Figs..30 to 33,thus forming the flat tortuous tube referred to. From the matchingorassembling rolls 82 the corrugated sheets pass rearward to the seamingdevices which will now be described.

By referring particularly to Figs. 12 to 16, it will be'seen that in therear end ofthe machine between the side frames 41 a carrlage 83 ismounted to reciprocate horizontally longitudinally of the machine, thiscarriage having-at its endsrollers 84 which en gage cams fastened to theshaft 52, and

by means ofwhich cams the carriage is given its characteristic movement.The carriage 83 mounts the lower seamer jaw 86 which is connected withthe carriage at its 'endsby means of guide devices 87, shown best inFig. 13, the carriage moving the jaw longitudinally of the machine andthe jaw being 'capableof independent vertical movement seamer jaw 92 isin cross section in the form of an inverted U so that its lower sideedges meet the upper sideedges of the lower jaw I as shown.

(see Figs. 1.5 and 16). The lower side edges of the aw 92 are eachprovided with. tut groups of'regularly spaced teeth 93 corre-,

sponding to the corrugations of'the plates 0. and a, and adapted tointerlock with the corresponding groups of teeth '91, as shown in Figs.21-25.

The upper jaw 92 is attached to and carried by yokes 94' which arepreferably two in number; and are arranged F and 92. It, therefore,willappear that the upper seamingjaw mounted to'move vertically towardand from the lower jaw, and that its mounting we, actuating devices areindependent of thosebf the lower jaw exea cepting that both are actuatedfrom theshaft 52. It will also be seen, particularly with reference ToFigs. 15,16, 17, '18 and 20 that the side edges of the lower seamer jawproject out beyondeethe' outer face of the sides of the upper Qalillfi.""jaW forming ledges exposed by the upper jaw, which ledges are used-inthe seaming--operation as will be hereinafter set forth."

Coacting. with each of the seamer jaws are two stripper plates 98.and99, which perform essentially the function of the strippers 67 beforedescribed. The stripper plat-es 98 and 99 lie between the seamer jaws 86and 92 and are formed with toothed side edges 98 and .99 (see full linesin Figs.

20 25, and the broken lines in Figs. 15 and 16). These teeth 98 and 99match with the teeth 91 and 93 and set between the same;

It follows, therefore, that the stripper plates are arranged in twopairs,

the members of each of which face each other and are engagedrespectively with the upper and lower jaws. Attached to one tooth ateach end of each stripper plate, as shown by the broken lines in Figs.13, 15 and 17, and the full lines in Fig; 20, are pins 1.00 which slidefreely in the sidewalls of the seamer jaws 89 and 92., *and are pressedinward by springs 101. These devices tend to move the strippers 98 and99 outward from their corresponding jaws, as shown with respect to thestripper 98 in Fig. 21, and 99 in Fig. 24. -Tl;e action of the strippcrsis controlled, however, by the seamer guide which comprises top andbottom walls 102 extending freely through the space between the sidewalls of the upper and lower seamer jaws and projecting beyond each endof said. jaws, the projecting ends of the upper and zlower walls 102being joined by check plates 103 (see Figs. 13 and 24.) thus forming ofthe elements 102 and 103 a. rigid boX-like structure which is movableindependently of the seamer jaws, and through which the corrugatedplates ,pass snugly so that "vertical movement of the guide willcorrespondingly move the plates a, and a.

Asshown best in Fig. 13, the parts 102 of the. seamer guide havecavities 102? formed therein to accommodate the strippers 98 and 99',the otherportions of the inner surfaces ofthe' said parts 102 beingplane to engage the plates a and a as described. The seamer guide isjoined to the upper strippers 98 by means of headed pins ,98 which arefastened to the strippers 98 and extend loosely through the upper late102 of the seamer guide, and said gui e is joined to the lower stripper99 bymeans of pins 99 which extend loosely through slots 102.,in thelower plate 1020f the scanner guide, the slots 102 runninglongitudinally of the guide so that the guide and the strippers .98 and99 may move vertically relatively to'the jaws 92 and -86,'while thelower jaw 86 with the stripper .99owing to the slots 102 is capable ofmoving longitudinally relatively to the seamer guide'and jaw 92. Saidbox-like structure forming the seamer-guide is provided at each end withupwardly project in lugs 104 having keeper orifices therein. ith theorificed lugs 104C latches 106 co'act.

These latchesare best shown in Fig-.12 and are pivotally mounted on theupper seamer jaw 92in a horizontal position. Springs v 107 haveconnection-with the latches, which springs 'tend to engage the bent ends108 with the walls of the orifices 105 when the s eamer'guide is in therelatively raised position shown in Figs. 13 and 24. The latches .106movingvertically with the upper jaw 92 have their ends opposite the bentends 108 designed to coact with cam fingers 109. These cam fingers asshown best in Figs. 12 and 1 1 are mounted on the right-hand side of theframing of the machine, preferably through the medium of boxes 110 atsaid side of the machine in which operate the seaming fingers, as willbe hereinafter fully set forth.

Said latches, therefore, are normally engaged with the keeper lugs 104,but when the seamer guide drops to the position shown, for example, inFigs. 14 and 22 the latches engage the cam fingers 109 and 'are throwninto inactive position. By means of these latches the seamer guide islocked with the upper jaw 92 during certain periods of the operation,and when the latches are inactive the guide with the connected strippersand the plates (I. and a are dropped below their first position to thatshown in Figs. 21 and 22. In the first position the guide holds theupper strippers 98 engaged between the teeth 93 of the upper jaw, andthe strippers 99 move outward to the ends of the teeth 9] of the seamerjaw 86, and in the serond position the order is reversed, the strippers98 being moved outward to the ends of the teeth 93 and the strippers 99being moved inward between theteeth of forward pair of boxes 110 (seeFigs. 12,

17, 18 and 20). These fingers 111 are located respectively at the endsof the front pair of strippers 98 and 99. Reference to 30 will show thatthe horizontal or.

longitudinal parts "of the lower plate a which are bent over the plate ato form the seams shown in Fig. 31', lie intwo planes, and toaccommodate this'the working ends of the seamer fingers 111 are formed"with two working surfaces 111 and 111 'arranged at different elevationscorresponding respectively to the elevations of the said two parts ofthe plate a, so that as the seamer jaws move vertically they will .thensimultaneously engage two adjacent horizontal or longitudinal bends ofthe plate a with the seamer finger at each side of the ma chine. Saidseamer fingers are arranged to reciprocate horizontally in the boxes110, and this is effected as shown best in Fig. 15

by means of elbow levers 112 fulcrumed on brackets 113 projecting fromthe side frames 41, a. horizontal arm of the elbow levers 112 extendingthrough openings in the side frames and being joined together by apin114 which also carries a roller 115 engaged by a cam 116 on the shaft52.

117 indicates springs which throw the elbow levers against the cam andby this i means a regular periodic in and out movement is imparted tothe seamer fingers 111.

The vertical seamer fingers 118 seam the vertical bends of the radiatorsection which bends are shown in Fig. 31 in the position they assumeprior to the seamer operation. These fingers 118 are arranged in pairs,one

pair at each side of the machine, and are mounted in the rear boxesrespectively opposite the ends of the rear pair of strippers 98 and 99.The vertical or transverse seamer fingers 118 are movable bothlongitudinally and laterally in the rear boxes 110, and, as shown bestin Figs. 12 and 28, these fingers are provided with angular slots 119receiving pins 120 held stationary in the boxes 110, so that as thefingers are reciprocated longitudinally of themselves and transverselyof the-machine, the walls of the slots 119 running on the pins 120 willcause the fingers to move toward and from each other enabling them toset on the vertical or
